Incorporating Google AdMob Ads into your app is a three step process:
- Add the SDK JAR to your Eclipse project.
- Declare
com.google.ads.AdActivity in AndroidManifest.xml.
- Set up required network permissions in the manifest.
Adding the SDK JAR
The decompressed SDK consists of a JAR, a javadoc folder and a README.
1. Right click on your app project in Eclipse and choose Properties.
2. Select Java Build Path and the Libraries tab. Then click Add External JARs... to add the Google AdMob Ads JAR.
com.google.ads.AdActivity
The AdMob Ads SDK requires that
com.google.ads.AdActivity be declared in your app's
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.company"
android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name"
android:debuggable="true">
<activity android:label="@string/app_name" android:name="BannerExample">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application> </manifest>
Permissions
Making ad requests requires the networking permissions
INTERNET and
ACCESS_NETWORK_STATE, so these must also be declared in the manifest:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.company"
android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name"
android:debuggable="true">
<activity android:label="@string/app_name" android:name="BannerExample">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> </manifest>
You should now be able to rebuild your project without any errors.
Adding a com.google.ads.AdView
Android apps are composed of
View objects, Java instances the user sees as text areas, buttons and other controls.
AdView is simply another
View subclass displaying small HTML5 ads that respond to user touch.
Like any
View, an
AdView may be created either purely in code or largely in XML.
The five lines of code it takes to add a banner:
- Import
com.google.ads.*
- Declare an
AdView instance
- Create it, specifying a unit ID—your AdMob publisher ID
- Add the view to the UI
- Load it with an ad
The easiest place to do all this is in your app’s
Activity.
import com.google.ads.*;
public class BannerExample extends Activity {
private AdView adView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Create the adView
adView = new AdView(this, AdSize.BANNER, MY_AD_UNIT_ID);
// Lookup your LinearLayout assuming it’s been given
// the attribute android:id="@+id/mainLayout"
LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout);
// Add the adView to it
layout.addView(adView);
// Initiate a generic request to load it with an ad
adView.loadAd(new AdRequest());
}
@Override
public void onDestroy() {
if (adView != null) {
adView.destroy();
}
super.onDestroy();
} }
Warning: Make sure you're in test mode during development to avoid being disabled for clicking your own ads. See the
Best Practices guide for more details on enabling test ads.
You can download an example project containing this code
here and may alternately
create your banner in XML.
The Result
When you now run your app you should see a banner at the top of the screen:
Note: The very first time AdMob sees your publisher ID it may take up to two minutes to receive an ad. This initial two minute lag will recur every time the ID goes unused for 24 hours.
Warning: All new Android apps created after October 14, 2011 will require an
AdMob SDK that was released on or after March 15, 2011. This corresponds to version 4.0.2+ for Android. If you downloaded the library from our
official download site, then you're already set. Otherwise you may have an old version of the AdMob SDK that was released prior to March 15, 2011, and your new app will not receive any ad impressions until you update your SDK.
